Submit FCC Form 605 through electronic filing in ULS. There is no proof of passing certificate requirement for an RR. Per Public Notice DA 15-72, the FCC no longer mails license authorizations. If you provide an email address on your application, a link to print your official copy of your license will be automatically emailed to you when the application has granted. Licensees may also log into ULS to download official authorizations. Instructions can be found at How to Obtain Official Authorizations from ULS. Please file in ULS to replace a lost, stolen, or mutilated license.
